Three operating issues I noted with LPG gensets...
1. Expect about 80% total power from the engine
2. LPG engines operate significantly hotter than gasoline engines.
3. Weird City: LPG engines develop more lube oil gasket leaks.
The cons and pros are extensive. Greater gallonage fuel consumption, fuel harder to find, remote. Containers are heavy and bulky. Engines run cleaner, fuel never goes bad, no fuel pump, spark plugs last much longer, oil stays clean like new.
Suggestion: Review the above, keep the points in mind (especially the positive ones) use the generator and come to your own conclusion. No one can decide this but you. Don't let anyone else "decide" for you.
